ome from outer space. Kirk disagrees. Kirk says that gamma rays are not as dangerous as ultraviolet waves since they cause sunburn. Who is right and why?

Neither are right because X-rays have radiation and are the most dangerous. That is why you have to wear a lead vest when you get dental x-rays.


Neither are right. Microwaves are the most dangerous because they have the longest wavelength and the biggest frequency. Microwave kill all living things.

These rays have the most energy and can go through six feet of concrete and damage your DNA as well. The higher the energy waves (gamma, x-ray), the shorter the wavelengths
